SECTION 26-1.0: SCOPE This Chapter applies to shackles. SECTION 26-1.1: TYPES AND MATERIALS 26-1.1.1 Types (a) Body types covered are anchor, chain, and syn- thetic sling (see Fig. 26-1.1.1-1). (b) Pin types covered are screw pin and bolt type (see Fig. 26-1.1.1-1). (c) Shackles other than those detailed in this chapter shall be used only in accordance with recommendations of the shackle manufacturer or a qualified person. NOTE: Round pin shackles are not covered by the scope of this volume, because they have limited application in lifting. They are only restrained by a cotter pin and may present a hazard in odd angle loading conditions. 26-1.1.2 Materials The shackle shall have sufficient ductility to perma- nently deform before losing the ability to support the load at the temperatures at which the manufacturer has specified for use. SECTION 26-1.2: DESIGN FACTOR (a) The design factor for shackles up to and including a 150 ton (136 metric ton) rated load shall be a minimum of 5. (b) The design factor for shackles over 150 ton (136 metric ton) rated load shall be a minimum of 4. SECTION 26-1.3: RATED LOADS Rated load shall be in accordance with the recommen- dation of the shackle manufacturer. The terms “rated capacity” and “working load limit” are commonly used to describe rated load.
SECTION 26-1.5: IDENTIFICATION 26-1.5.1 Shackle Body Identification Each new shackle body shall have forged, cast, or diestamped markings by the manufacturer to show (a) name or trademark of manufacturer (b) rated load (c) size 26-1.5.2 Shackle Pin Identification Each new shackle pin shall have forged, cast, or diestamped markings by the manufacturer to show (a) name or trademark of manufacturer (b) grade, material type, or load rating 26-1.5.3 Maintenance of Identification Shackle identification should be maintained by the user so as to be legible throughout the life ofthe shackle. SECTION 26-1.6: EFFECTS OF ENVIRONMENT 26-1.6.1 Temperature When shackles are to be used at temperatures above 400°F (204°C) orbelow −40°F (−40°C), the shackle manu- facturer or a qualified person should be consulted. 26-1.6.2 Chemically Active Environments The strength of shackles can be affected by chemically active environments, such as caustic or acid substances or fumes. The shackle manufacturer or a qualified per- son should be consulted before shackles are used in chemically active environments. SECTION 26-1.7: TRAINING Shackle users shall be trained in the selection, inspec- tion, cautions to personnel, effects of environment, and rigging practices as covered by this Chapter.
26-1.8.1 Initial Inspection Prior to use, all new, altered, modified, or repaired shackles shall be inspected by a designated person to verify compliance with the applicable provisions of this Chapter. Written records are not required. 26-1.8.2 Frequent Inspection (a) A visual inspection shall be performed by the user or other designated person each day before the shackle is used. Rigging hardware in semi-permanent and inac- cessible locations where frequent inspections are not feasible shall have periodic inspections performed. (b) Conditions such as those listed in para. 26-1.8.4 or any other condition that may result in a hazard shall cause the shackle to be removed from service. Shackles shall not be returned to service until approved by a qualified person. (c) Written records are not required. 26-1.8.3 Periodic Inspection (a) A complete inspection of the shackle shall be per- formed by a designated person. The shackle shall be examined for conditions such as those listed in Section 26-1.8.4 and a determination made as to whether they constitute a hazard. (b) Periodic Inspection Frequency (1) Periodic inspection intervals shall not exceed 1 yr. The frequency of periodic inspections should be based on (a) frequency of shackle use (b) severity of service conditions (c) nature of lifting or load-handling activities
